the game in question was not made for PC (to my knowledge) and the quote is not as much said as badly sytesysed sound effect (still I think anyone who hears it would recognise the words). it's allso the only thing ever said.

since alot of time passed.... here is one: "We never took heed to the ancient prophecies. And like fools, we clung to our old hatreds." (Might have screwed up on the clung part).

I know I've heard that quote somewhere...

It's not fallout (unless it is)...
Diablo?

very clsoe, but wrong game.

well I suppose it can't be wasteland (there were no spoken quotes), so:
Warcraft.

correct, Warcraft III actully, its in the intro where the orc and human fight, when an infernal crashs into the ground from the sky (narriator says: "When the sky rained fire").

I don't have many games with audible dialogues in them, so:
"the end of the world has ocured pretty much as we had predicted: to many people, and not enough space or resources to go around"

eeeeeeh...ummmmmm.....Fallout 1 maybe?
Im seriously confused

no, try again.

Fallout 2.
